APPARATUS FOR ATOMIZING- LIQUIDS.

Application filed October 10,

To all whom it may concern:

Be it known that 1, PAUL KEsTNER, a citizen of the French Republic,residing at Lille, in the N 0rd Province of France, have invented newand useful Improvements in Apparatus for Atomizing Liquids, of which thefollowing is a specification.

This invention has reference to improvements in apparatus for atomizingliquids and simultaneously mixing them with air or gas,

taneous y mixing the atomized liquid in the form of mist with air orgas, for such pur poses as moistening air or washing gases.

Centrifugal fans have been commonly em ployed heretofore for thepurposes indicated,

ut the power required to drive them at the high speed necessary toaccomplish the atomization of the water is very considerable.

In my improved drum or wheel, the blades or wings of the centrifugal fanare replaced by sheet metal flat rings mounted parallel and very near toeach other and perpendicular to the axis of the drum.

It is well known that water when projected into fine particles, and. itwill be readily understood that in constructing a drum of a series offlat rings as described and employing means for spraying water on tothese rings from the interior of the drum I provide a very effectiveapparatus for atomizing water. At the same time a somewhat remarkableresult is attained in that such a drum or wheel displaces a considerablevolume of air when rotated at a high speed and this volume is in creasedby increasing the quantity of water injected. This displacement of air,which is accomplished with a small expenditure of power, is broughtabout partly by the rotation of the rings but more particularly by theinductiveaction of the water atomized at the periphery of the disks,between which the air is drawn. I

Referring to the accompanying drawing, Figure 1 shows my complete aparatus, the atomizing drum being shown in ongitudinal section, and Fig.2 is a cross section of the drum. Figs. 3 and 4 show in side elevationcases in which the atomizing fan is ada ted to operate depending u onthe use to w ich it is put as will hereinaffer be explained.

In Fig. 1, D, D are the fiat sheet-metal rings. They aremounted on barsor arms I Specification of Letters Patent.

T, and the drum thus formed is mounted on a disk P which is carried by ashaft A that rotates in bearings N and is provided with a pulley M. R isa nozzle by means of which water is s rayed regularly upon the rings Dthrough t 1e open end of the drum; this may be a simple expanding jet,as shown.

Fig. 2 shows one of the rings D. The arms T only serve to support andmaintain the rings inposition and may be ,of circular or any other crosssection.

Any number of rings may be connected together in the manner indicated toconstitute the atomizing drum. The nearer they are to each other and thegreater their number, the

greater will be the quantity of water which the drum will be capable ofbreaking up or atomizing, and the greater also will be the volume of airdrawn through between the" rings.

My improved atomizing drum may be mounted in the free air or in asuitable chamber. Or it may be mounted in an ordinary centrifugal-fansnail-shell casin as shown in Fig. 3in which E indicates the casing, Othe eye or air-intake, and U the outlet. The same drum or wheel may alsobe employed for separating a gas or a vapor from dust or water carriedalong therewith. In this case the-drum is mounted in a chamber or in asnail-shell casing, but instead of allowing the air, or the gas to bewashed, to circulate in the normal way, 'i. e. instead of the air beingdrawn through from the center towards the circumference it is forced inby mechanical means from the back, i. e. in the opposite direction,against the current created by the rotation of the drum. Fig. 4illustrates this application. Referring to this figure, D is anatomizing drum constructed in accordance with my invention mounted in asnailshell casing B. Air is forced in by mechanical means at U and makesits exit at 0; it is thus forced to pass between the fiat rings formingthe drum from the periphery towards the center. When water is sprayedinto this drum by means of a nozzle R as in Fig. 1, air forced throughbetween the rings as indicated has to pass through a counter current ofmist, Without being able to carry this along with it, for centrifugalforce acts against it and forces the mist constantly outwards, and theapparatus thus constitutes a very effective washer and at the same timea powerful separator.

, It will be understood of course that when the drum is to be used forthe purposes just referred to, the rings must not be mounted too near toeach other to cause an undue resistance to the passage of the countercurrent of air.

What I claim as my invention, and desire to secure by Letters Patent, is

1. An apparatus for atomizing liquids comprising a rotary carriage, andsupported to be rotated thereby a series of rings separated from oneanother and parallelly arranged at right angles to the axis of theirrotation.

2. An apparatus for atomizing liquids comprising a rotary carriage, andsupported to be rotated thereby a series of flat rings separated fromone another and parallelly arranged at right angles to the axis of theirrotation, said carriage being adapted in part to close one end of thechamber formed Within said rings.

3. An apparatus comprising a rotary disk,

for atomizing liquids a series 'of flat .rings connected therewith to berotated thereby, said rings being separated from one.

I l l right angles another and parallelly arranged at right angles tothe axis of their rotation.

4. An apparatus for atomizing liquids comprising a rotary disk, armsextending therefrom, a series of flat rings mounted upon said arms to berotated by. said disk, said rings being separated from one another andparallelly arranged at right angles to the axis of their rotation.

5. Apparatus for atomizing liquids, consisting of a drum made up of anumber of flat rings arranged parallel to each other at orperpendicularto the axis of the drum and carried by arms projecting froma disk mounted on a rotatable shaft, and means for-spraying liquid on tosaid disks substantially as set forth.
